Accidents caused by rock bursting in underground excavations in the Peruvian mining sector pose a critical problem, leading to fatalities, machinery damage, and complete tunnel collapse. As mining activities reach greater depths, evaluating rock bursting becomes crucial. Various support systems have been employed to counteract these events, including dynamic bolts, dynamic mesh, and shotcrete on the slab. This research analyzes how these supports respond when rock mass releases accumulated energy under different conditions. Understanding their performance is vital for selecting appropriate reinforcement measures to enhance safety and mitigate the impact of rock bursts in underground mines.

In this research, we will focus on analyzing the influence of the rains on mining companies in the district of San Marcos in the department of Ancash, Peru. To do in this investigation, a stability analysis of slopes with limit equilibrium methods, being the Janbú the one selected for said study. On the other hand, it calculated the probability of failure of the slopes using methods probabilistic such as Monte Carlo. Such studies mentioned were applied with the help of the Slide software.

The open-pit mining industry is vital to the global economy, facing challenges in operational efficiency and cost management. Fleet sizing is crucial for optimization, requiring innovative approaches. Discrete event simulation using Arena software addresses fleet sizing complexities in open-pit mines, aiding in understanding operational delays and high costs. This research aims to develop a framework integrating process modeling and simulation in Arena, enabling real-time fleet decisions. The study reviews mining process simulation literature, open-pit mine characteristics, and proposes detailed models for geology, topography, and mining operations. Critical variables like equipment performance, productivity, and truck hours will be evaluated. Results aim to provide mining companies a valuable decision-making tool for efficient resource management and cost reduction. The study also explo...

The representative sample of low grade sulphide ore gold for this research study comes from the province of Casma Ancash department. The characterization of the sample was analyzed in the polarized light microscope, in the EAP. Geological Engineering at the National University of San Marcos (UNMSM), the results indicated the presence of the following mineralogical species such as Electrum, sphalerite, ilmenite, pyrite, hematite, goethite and bargains. Furthermore we found particles referred to gold, which are: Electrum-goethite, Electrum-Gangas, Electrum-goethite-Gangas. Based on the results of the characterization we realized metallurgical process like preconcentration Falcon performed in the concentrator, the results of the most representative process is 67.80%, obtaining in a granulometry of -200mesh, obtaining a concentrate grade of 16.20 g / TM, 57.04% of 41.60 radio recovery and co...

La muestra representativa del mineral sulfurado de baja ley de oro, para el presente estudio de investigación, proviene de la provincia de Casma, departamento de Áncash. La caracterización de la muestra se realizó en el microscopio óptico polarizado, de la EAP Ingeniería Geológica de la Universidad Nacional Mayor de San Marcos (UNMSM). Los resultados de esta caracterización indicaron la presencia de las siguientes especies mineralógicas: electrum, esfalerita, ilmenita, pirita, hematita, goethita y gangas. Además, en la muestra encontramos partículas entrelazadas referidas al oro, las cuales son: electrum-goethita, electrum-gangas, electrum-goethita-gangas. Según los resultados de la caracterización, se realizaron pruebas metalúrgicas de preconcentración a la muestra, con el equipo de concentración Falcon; los resultados de la prueba más representativa obtenida a una gran...
